Axelnomad: Is there any other way other then gameranger? A buddy and I have been trying to get back into heroes 3, but gameranger does not seem to work for us despite what we try to do.
A bit late with reply, but here it is:
While using Gameranger to play HoMM3 over internet, me and a friend of mine experienced lots of troubles before we got it working.
The fact that one can host / join a game while another one only join is related somehow (we haven't figured it out how) to the fact that my friend plays the game with a wireless connection.
The fact that I couldn't even host a game in the first place was due to my antivirus / firewall software. I added the game to the exceptions list, and we can play now.
